Precision measurement of the $^{176} Lu^{+}$ $^{3} D_{1}$ microwave clock transitions

M. D. K. Lee, Qi Zhao, Qin Qichen +4

We report precision measurement of the unperturbed $^{3} D_{1}$ microwave transition frequencies in $^{176} Lu^{+}$ to a fractional uncertainty of $4 \times 1 0^{- 14}$ . We find t…

Validating a lutetium frequency reference

Kyle J. Arnold, Scott Bustabad, Qin Qichen +3

We review our progress in developing a frequency reference with singly ionized lutetium and give estimates of the levels of inaccuracy we expect to achieve in the near future with…

Enhanced micromotion compensation using a phase modulated light field

K. J. Arnold, N. Jayjong, M. L. D. Kang +4

We investigate sideband spectroscopy of a trapped ion using a probe laser phase modulated at the trap drive frequency. The enhanced sensitivity of our technique over traditional si…
